How do we know that universe is expanding with the speed more than speed of light even we know that nothing can move faster than the speed of light?
What I suppose is-
Assume that a person standing at the back of the one way infinite bus which is moving at 40 km/h. It is presumed that nothing inside can travel faster than 40 km/h not even the edges of the bus.
Now, say an observer is standing outside the bus and observing that person inside. According to him, the person is moving with 40 km/h.
Now the person start moving at 10 km/h in the same direction of the bus. In this scenario the bus would get slow down to 30 km/h so that the observer sees the person still moving at the speed of 40 km/h. Moreover, the length of the bus would also be contracted so that observer sees the person still at the back of the bus with the specific body posture.
1. Don't this experiment state that space-time are communicating with the observer such that the observer is experimenting something like for a quantum weird world.
2. I also think that all the object have their space-time frame with them that is moving at c and we are just enjoying and expressing the relativeness.
3. All the mass is relative to us but in reality all of us are actually a energy.
Now as per my assumptions I want to ask-
"Are we inside a photon that is moving at c in the vacuum?"
And if we know the answer, what this information can help us to do next?
Hi Harshal,
I have few considerations I would like you to consider. In a context such like your example there is, in my view, no room to conjecture 2. and 3. As massive bodies we are equivalent to a certain amount of energy but we are NOT energy in that sense. Specifically none of us can travel at c. That is from the perspective of relativity a limiting velocity that we, as massive bodies, cannot reach. This is one of the consequences of E=mc>2. does it sound?
Thanks sir Arkady L. Kholodenko and Angelo Cei for giving an insight over my weird thought.
Sir Arkady L. Kholodenko, to answer your beautiful question I just want to take you through the theory of "The Arrows of Time" especially "The thermodynamic Arrow" and "The Psychological Arrow" that has been entitled in The Theory of Everything.
The core heart of these arrows conclude the "Time increases with the Disorderliness". because unconsciously, we are measuring the time in which the Disorder increases.
Coming to the point, If we know about the inside scenario of the photon we can create a dummy or artificial Time by disordering the happening inside it exactly same as our up-till known universe through programming as "observer" in my example. Moreover, probably we can see the future by speeding up the disorderliness.(Although I realize the it not that easy as I write)
Sir Angelo Cei Yes, you are correct with perspective of relativity that no massive body can reach at c. Also, in my example I never tried to conclude that we are moving at c or we can move at c instead I wanted to state that the virtual one way infinite bus ("Space-time") is moving at c and it is being programmed by the observer to do such a time Dilation and length contraction to maintain its speed c.
Relative mass Transformation states m = m0/sqrt(1-(v**2/c**2)) where m0 is the rest mass. which tells that at "v -> c" m would reaches near to infinite and the E = m(c**2) would also get to infinite. Can't we think that we are the part of that infinite energy ? as we(space-time) is also moving at c.
